Physician Bio

The chance to help people and make their life easier is what I find most rewarding about being a doctor. I really enjoy talking to my patients, answering their questions, and helping them stay healthy. I chose internal medicine because I want to provide complete care to my patients. For instance, when my patients are admitted to the hospital or a nursing home, I continue to be involved in their care and visit them regularly. I believe in the importance of having one doctor follow you throughout your life, meeting your health needs.
